After further investigation, it appears that the problem lies in the order of the application of 
RenderTransform to OpacityMask and Clip. The XPS spec is fairly unclear on the matter, and it's not 
made any easier by the fact that these things can be specified either as attributes or as child tags, in 
any mix.

Examples:

<Canvas OpacityMask="...">
<Canvas.RenderTransform />
...

versus

<Canvas RenderTransform="...">
<Canvas.OpacityMask="..." />
...

versus

<Canvas RenderTransform="..." OpacityMask="...">
...

versus

<Canvas OpacityMask="..." RenderTransform="...">
...
